International Standards:
- ASME B16.5(U.S. Standard): Class 150 or lower pressure ratings.
- EN 1092-1(European Standard): PN6 to PN16.
- JIS B2220(Japanese Industrial Standard):pressure ratings of 5K, 10K, 16K, 20K
- GOST 12820-80(Russian/CIS Standard):pressure ratings of 0.1 MPa to 2.5 MPa
- SABS 1123(South African Standard): PN6 to PN16.
- DIN 2573 : PN6 to PN16.
- BS 4504(British Standard): PN6 to PN16.
Pros：
- Low Cost: Simple design with minimal material usage.
- Easy Installation: No precise alignment required, ideal for rapid assembly.
- Versatility: Suitable for most low-pressure scenarios.
Cons：
- Lower Strength: Welds directly bear medium pressure, prone to fatigue.
- Unsuitable for High Pressure/Temperature: Prolonged high pressure or thermal cycling may cause weld cracks.
Description
This type of flange is a flat, plate-like component used in piping systems, designed to be welded directly to the end of a pipe for connection. It is typically employed in low-pressure applications due to its simple structure and cost-effectiveness.
